STMicroelectronics has introduced AEC-Q100 Grade-0 op amps and comparators in the space-saving MiniSO8 package, giving automotive designers twice the freedom to miniaturise ECUs deployed in the most extreme temperature environments and safety-critical systems.

The LM2904WHYST dual op amp and LM2903WHYST dual comparator in 4.9mm x 3.0mm MiniSO8 are qualified for operation from -40°C to 150°C, with the added advantage of 50 percent smaller footprint than other Grade-0 parts in standard SO8.

The wide ambient operating temperature range of these ICs ensures robust and resilient performance in systems that are exposed to the harshest conditions. These include under-the-hood electronics such as engine controllers, in-gearbox modules, LED-lighting controllers, and safety-critical systems such as ABS controllers that must provide absolute dependability.

The new parts are developed with the benefit of ST’s extensive experience working with major automotive Tier-1 suppliers, and can be individually tested up to 150°C as part of Production Part Approval Process (PPAP) tests. As high-quality industry-standard LM2903 and LM2904 devices, they deliver benchmark performance compared to familiar metrics including input bias current, input offset voltage, current consumption, and supply-voltage range.

The LM2904WHYST and LM2903WHYST are in production now, priced from $0.76 for orders of 1000 pieces.
